British dance legends The Chemical Brothers have been told the ending to Game Of Thrones by the show’s cast.

U.S. network HBO’s hit fantasy drama comes to an end after eight action-packed seasons this Sunday, with viewers still unsure as to who will end up on the Iron Throne as the ruler of the fictional kingdom of Westeros.

However, the finale won’t be a surprise to Chemical Brothers bandmates Tom Rowlands and Ed Simons, as several members of the cast joined them at a gig in Spain in October and let slip details of the ending.

“Then they were all in the dressing room and they were just telling me stuff about what happened in the show,” Simons, who hasn’t followed the show, tells Australian website Music Feeds. “So I kind of know things about what’s gonna happen at the end… Well, I didn’t actually understand what they were telling me. I told Tom something and he was like, ‘Wow, that’s quite big…’”

Explaining how he and his bandmate found out TV’s most closely guarded secret, he added: “They all came to a show in Spain, the whole cast, because we’re friends with Alfie Allen (who plays Theon Greyjoy). So Daenerys (Targaryen, actor Emilia Clarke) and Jon Snow (portrayed by Kit Harington) and all these people were in our dressing room. They came to the show and they were all in the front row… The crowd just went crazy when they came in.”

Simons has known Allen for years, having dated his sister, British pop star Lily Allen, more than a decade ago.

Game of Thrones fans were left in shock by the penultimate episode on Sunday, as Daenerys, who has been one of its heroes since the first season, took a dark turn setting her dragon on the city of King’s Landing, killing thousands in a murderous rampage.
